How do you find an equal ratio for example is 63:27 14:6 a equivalent ratio?
Answer:
Step-by-step explanation:
Find a common denominator or greatest common factor. 63 and 27 are both multiples of 9. When you divide each by 9 you get 7:3. 14 and 6 are both multiples of 2. When you divide each by 2 you get 7:3 again. So these ratios are equivalent.
Start with any set of numbers. Multiply them each by the same factor and the new set will be an equivalent ratio.
Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
y - 12 = -(x + 2)
y + 12 = -(x - 2)
y + 12 = 3(x - 2)
y + 12 = -3(x - 2)
Answer:
y + 12 = 3(x-2)
Step-by-step explanation:
To start, you want the slope of the other line. Well, the slope of a parallel line is the same, so since the first line's slope is 3, so will the other one. then, because there is no other answer with a slope of 3, you automatically know it is the third answer. you don't need to work this problem further, but if you need to in the future, just comment and I will help you.

Marge has 4 more than 2 times as many books as Susan. If Marge has 22 books and x is the number of books that Susan has, the relationship can be written as 4 + 2x = 22. How many books does Susan have?
Susan have 9 books.
Explanation:
Given that Marge has 4 more than 2 times as many books as Susan.
Let x represents the number of books that Susan has.
The relationship is written as
[tex]4+2x=22[/tex]
To find: Number of books that Susan have.
The number of books that Susan have can be determined by solving the expression for x.
Thus, we have,
[tex]4+2x=22[/tex]
Subtracting 4 from both sides of the equation, we get,
[tex]2x=18[/tex]
Dividing both sides by 2, we get,
[tex]x=9[/tex]
Therefore, Susan has 9 books.
A slot machine has 3 dials. Each dial has 30 positions, one of which is "Jackpot". To win the jackpot, all three dials must be in the "Jackpot" position. Assuming each play spins the dials and stops each independently and randomly, what are the odds of one play winning the jackpot?
1/30 = 0.03 or 3%
3/(30+30+30) = 3/90 = 0.33 or 33%
3/(30×30×30) = 3/27000 = 0.0001 or 0.01%
1/(30×30×30) = 1/27000 = 0.00003 or 0.003%
Answer:
3/(30×30×30) = 3/27000 = 0.0001 or 0.01%

Step-by-step explanation:
Which statement is FALSE for this situation?
A) A linear function represents Company A's payments.
B) An exponential function represents Company B's payments.
C) Company A's payments grow by a factor of 2.
D) Company B's payments grow by a factor of 2.
Option C: Company A's payments grow by a factor of 2
Explanation:
We need to determine the statement which is false.
Option A: A linear function represents Company A's payments.
From the table, it is obvious that the y - value increases by adding 5000.
Thus, the payments of company A can be written in linear function.
Hence, the statement a linear function represents Company A's payments is true.
Therefore, Option A is not the correct answer.
Option B: An exponential function represents Company B's payments.
From the table, it is obvious that the y - value increases by a factor of 2.
Thus, the payments of company B can be written in exponential function.
Hence, the statement an exponential function represents Company B's payments is true.
Therefore, Option B is not the correct answer.
Option C: Company A's payments grow by a factor of 2.
From the table, it is obvious that the y - value increases by adding the 5000.
Hence, the statement Company A's payments grow by a factor of 2 is false.
Therefore, Option C is the correct answer.
Option D: Company B's payments grow by a factor of 2.
From the table, the y - value increases by a factor of 2.
Hence, the statement Company B's payments grow by a factor of 2 is true.
Therefore, Option D is not the correct answer.
If the base angle of the cone needs to measure 60° and the cone needs to be 24 inches tall, approximately how wide will the base of the resulting cone need to be?
A.
27.72 inches
B.
13.86 inches
C.
41.57 inches
D.
83.14 inches
Final answer:
Using the base angle and the height of the cone, we can use trigonometry to find that the width of the base of the cone needs to be approximately 41.57 inches, making option C the correct answer.
Explanation:
The question asks for the width of the base of a cone given that its base angle is 60° and its height is 24 inches. To solve this, we need to understand that the base angle of 60° creates a right-angled triangle when a line is drawn from the apex of the cone to any point on the base's circumference, with the height of the cone being one side of this triangle and half of the cone's base width being the other side.
Using trigonometry, specifically the tangent function, which is the opposite side (half the base width) over the adjacent side (height), we can solve for the base width. Given that tan(60°) = √3 and the height is 24 inches, the formula becomes √3 = (base width/2) / 24, solving for the base width gives us roughly 41.57 inches, which makes option C correct.

Select the best answer from the choices provided.
A. EF is parallel to the bases.
B. EF = 2(AB + DC)
C. 1/2EF = AB + DC
D. EF =1/2(AD + CB)
Answer:
The answer is A
Step-by-step explanation:
There is no way to prove any of the others to be true
Final answer:
The median EF in an isosceles trapezoid is parallel to its bases, making option A the correct answer.
Explanation:
The student asked a question related to properties of an isosceles trapezoid and its median. In an isosceles trapezoid, the median is a line segment that connects the midpoints of the non-parallel sides. The properties of a trapezoid's median include that it is parallel to the two bases and that its length is equal to the average of the lengths of the two bases. Therefore, the correct statement from the list provided is that the median EF is parallel to the bases.
For more clarity:
EF is indeed parallel to the bases AB and CD; this corresponds to option A.EF is not twice the sum of the lengths of AB and DC, so option B is incorrect.EF is also not half the sum of the lengths of AB and DC, which means option C is incorrect.The length of EF is not half the sum of the lengths of the non-parallel sides AD and CB, so option D is incorrect.Why is the reference angle the angle
the terminal side and the x-axis instead of the y-axis?
Answer:
If necessary, first "unwind" the angle: Keep subtracting 360 from it until it is lies between 0 and 360°. (For negative angles add 360 instead).
Sketch the angle to see which quadrant it is in.
Depending on the quadrant, find the reference angle:
6 yd
11 yd
16 yd

value Rent-A-Car rents a luxury car at a daily rate of $37.25 plus 20 cents per mile. A business person is allotted $110 for car rental each day. How many miles can the business person travel on the $110
Answer:
110- 37.25=72.25
72.25 divided by .20 =361.25
but since you can not drive part of a mile it would be 361 miles in one day.
Step-by-step explanation:
Final answer:
After subtracting the fixed daily rental rate from the daily budget and dividing the remainder by the cost per mile, it is calculated that the business person can travel 363.75 miles with the $110 budget.
Explanation:
To calculate how many miles the business person can travel on the $110 budget using the daily car rental rate provided, we can set up an equation based on the cost structure of Value Rent-A-Car. The rental cost consists of a fixed daily rate plus a variable cost per mile.
The fixed daily rate is $37.25, and the cost per mile is $0.20 (20 cents). With a daily budget of $110, we first subtract the fixed rate from the daily budget to find out how much money is left for the variable cost per mile:
Daily budget for miles = Total daily budget - Fixed daily rate
Daily budget for miles = $110 - $37.25
Daily budget for miles = $72.75
Now, we divide the money left for miles by the cost per mile to find the number of miles the business person can travel:
Number of miles = Daily budget for miles / Cost per mile
Number of miles = $72.75 / $0.20
Number of miles = 363.75 miles
The business person can travel 363.75 miles on the daily budget of $110, given the cost structure of the car rental.

Rani and her friends are raking leaves as a part of a school service project. The regular price of the supplies they need is 60$,but the store manager is giving them a 20% discount. Rani wants to know the sale price of the supplies.
Rani and her friends can purchase their supplies for $48 after a 20% discount on the original price of $60.
Explanation:Rani and her friends need to calculate the sale price of the supplies after a 20% discount. The original price is $60, and the discounts amount in money can be determined by multiplying this original cost by 20% or 0.20. This gives you a discount amount of $12. To determine the final price after the discount, you subtract the discount amount from the original price. Therefore: $60 - $12 = $48. Hence, the sale price of the supplies that Rani and her friends need is $48.

The lengths of two sides of a triangle are 26
meters and 48 meters. What is the range of
possible lengths, in meters, for the third side,
x, of this triangle? Write your answers in the
boxes.
Answer:
[tex]22\ m < x < 74\ m[/tex]
Step-by-step explanation:
Let
x ----> the length for the third side
we know that
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
Applying the triangle inequality theorem
1) [tex]26+48> x[/tex]
solve for x
[tex]74> x[/tex]
Rewrite
[tex]x < 74\ m[/tex]
2) [tex]26+x>48[/tex]
solve for x
subtract 26 both sides
[tex]x> 22\ m[/tex]
therefore
The range of possible lengths, in meters, for the third side is equal to
[tex]22\ m < x < 74\ m[/tex]
The range of the possible length of the third side of the triangle is 22 to 74 (exclusive)
Assume the lengths of a triangle are x, y and z.
The following are the possible inequalities that relate the side lengths
[tex]x + y > z[/tex]
[tex]y + z > x[/tex]
[tex]x + z > y[/tex]
The unknown side length is x.
So, we have:
[tex]x + 26 > 48[/tex]
[tex]48 + 26 > x[/tex]
[tex]x + 48 > 26[/tex]
Solve for x in the three inequalities
[tex]x + 26 > 48[/tex]
[tex]x > 22[/tex]
[tex]48 + 26 > x[/tex]
[tex]74 > x[/tex]
[tex]x + 48 > 26[/tex]
[tex]x > -22[/tex]
The values of x cannot be negative.
So, we ignore the inequality [tex]x > -22[/tex]
We are left with
[tex]74 > x[/tex] and [tex]x > 22[/tex]
Combine the inequalities
[tex]74 > x > 22[/tex]
Rewrite as:
[tex]22 < x < 74[/tex]
